In World of Warcraft, it is a rare ore used to make weapons and armor of uncommon, rare and epic grade. In The Dark Elf Trilogy by R. A. Salvatore set in the Dungeons & Dragons universe it is used to make drow weaponry. It is also used for armor in The Elder Scrolls III, and in the game Terraria it is
Chemical nomenclature, replete as it is with compounds with very complex names, is a repository for some names that may be considered unusual. A browse through the Physical Constants of Organic Compounds in the CRC Handbook of Chemistry and Physics (a fundamental resource) will reveal not just the whimsical work of chemists, but the sometimes peculiar compound names that occur as the ...
Xenotime is a rare-earth phosphate mineral, the major component of which is yttrium orthophosphate (Y P O 4).It forms a solid solution series with chernovite-(Y) (Y As O 4) and therefore may contain trace impurities of arsenic, as well as silicon dioxide and calcium.
Although aluminium is the third most abundant element and the most abundant metal in the Earth's crust, it was at first found to be exceedingly difficult to extract the metal from its various non-metallic ores. The great expense of refining the metal made the small available quantity of pure aluminium more valuable than gold. [16]
Wolframite ore exhibits massive form with a dark grey to reddish black coloration. [5] Wolframite in its pure crystal form exhibits a monoclinic crystal system with a perfect cleavage of {010} and an iron black color. Wolframite in its crystalline form also displays lamellar and prismatic habit. [10]
The traditional "rare-earth chloride", as a commodity chemical, was also used to extract the individual rare earths by companies that did not wish to process the ores directly. As of 2007 [update] , mischmetal is typically priced at less than 10 USD per kilogram, and the underlying rare-earth chloride mixtures are typically less than US$5/kg.
